Air Conditioners 
In Blue Ash, central air conditioning is the standard in most homes. These systems cool your entire home evenly through your ductwork, keeping every room comfortable no matter how hot it gets outside. At Hill-Air, we provide expert air conditioner services to keep your system running smoothly, efficiently, and reliably all summer long.
Air Conditioning Installation
Installing a new air conditioner in your Blue Ash home? We’ll help you choose the right system based on your home’s size, layout, and efficiency needs. Every AC is rated by SEER2 (Seasonal Energy Efficiency Ratio)—a higher SEER2 means lower energy bills. Our team ensures your system is properly sized, up to code, and professionally installed for quiet, consistent cooling that lasts.
Air Conditioning Maintenance
A yearly AC tune-up helps your system stay efficient and dependable through the summer. Ideally done in early spring, our maintenance includes checking refrigerant, cleaning coils, inspecting the blower, and testing all electrical parts. A well-maintained unit runs quieter and costs less to operate. With our maintenance plan, you’ll get regular tune-ups and priority service—no need to remember when it’s due.
Air Conditioning Repair
If your AC isn’t cooling well, makes strange noises, or starts leaking, something’s off. It could be anything from a clogged drain to a failing capacitor. We’ll run a complete diagnostic to find the issue and handle your AC repair, whether that’s replacing a part like a compressor, thermostat, or motor.
Air Conditioning Replacement
Air conditioners usually last 12 to 15 years. If yours is needing more repairs, struggling to cool evenly, or causing your electric bills to spike, it might be time for a replacement. We’ll assess your home’s needs, go over SEER2 options, and install a new system that fits just right. You’ll get more comfort, better efficiency, and peace of mind.
Air Handlers
Your air handler is the indoor side of your cooling or heat pump system. It’s what moves air through your ductwork to keep every room in your Blue Ash home at the right temperature. We offer complete air handler services to ensure steady airflow, consistent comfort, and top efficiency from your HVAC system.
Air Handler Installation
For new construction or upgrades, we’ll size your air handler to match your system and square footage. We also install variable-speed ECM motors, which adjust automatically for smoother airflow and better energy savings across your home.
Air Handler Maintenance
Air handlers need regular attention to stay in good shape. We’ll inspect the blower motor, clean the evaporator coil, tighten electrical connections, and check overall airflow. Annual service helps your system run better. Our maintenance plan covers your seasonal checkups to keep everything on track.
Air Handler Repair
Noticing weak airflow, unusual sounds, or rooms that won’t stay cool? These are signs your air handler may have a worn motor, dirty coil, or electrical issue. We’ll test every part to find the cause and get your cooling system back on track—fast.
Boilers
Boilers are a great fit for many homes in Blue Ash, offering quiet, steady warmth without blowing air around. Whether you have in-floor heating or traditional radiators, we offer full boiler services—from installation and maintenance to quick repairs—to keep your system working efficiently all winter.
Boiler Installation
If you’re building or upgrading to radiant heat, we’ll help you choose the right boiler based on your fuel source and AFUE (Annual Fuel Utilization Efficiency) rating. A 90% AFUE boiler, for example, turns 90% of its fuel into usable heat. We install and pipe your new system so you get even, long-lasting warmth throughout your home.
Boiler Maintenance
To keep your boiler safe and efficient, it needs annual service. We flush sediment, check burners, test safety controls, and inspect for corrosion or leaks. We also make sure your radiators or in-floor system are heating evenly. With our maintenance plan, boiler tune-ups are scheduled in the fall so you’re ready before the cold arrives.
Boiler Repair
If your home’s not heating, pipes are banging, or water is leaking, we’ll track it down—whether it’s a bad circulator pump, pressure valve, or ignition issue. We service both gas and oil boilers and handle everything from air in the lines to control board issues so your heat stays safe and steady.
Boiler Replacement
Boilers can last 15–25 years, but if yours is inefficient, leaking, or heating unevenly, it may be time to replace it. We’ll recommend a high-efficiency unit tailored to your home’s setup—radiators, baseboards, or radiant floors—for better heat, lower costs, and fewer repairs.
Ductless Mini Splits
Older homes in Blue Ash and finished spaces like basements or additions often don’t have room for ductwork. That’s where ductless mini splits shine. With small indoor units and a quiet outdoor compressor, they deliver efficient heating and cooling exactly where you need it. Our mini split services include installation, maintenance, and repair of ductless systems.
Ductless Mini Split Installation
Mini splits are ideal for rooms without ducts—like garages, offices, or second-story additions. They provide zoned control and are rated by SEER2 (for cooling) and HSPF2 (for heating). Many models reach 20+ SEER2, helping you save big on energy bills. We’ll help you choose the number of zones and install everything, from wall units to outdoor equipment.
Ductless Mini Split Maintenance
Even though they’re ductless, these systems still need upkeep. We clean or change the filters, flush condensate lines, check refrigerant levels, and inspect the outdoor unit. Seasonal maintenance keeps each zone efficient and reduces wear and tear. With our maintenance plan, we’ll handle it all for you.
Ductless Mini Split Repair
If your mini split isn’t cooling a room, starts dripping water, or the remote won’t work, there may be a blocked filter, low refrigerant, or a wiring problem. We’ll test everything—indoor and outdoor—to get your system running smoothly again.
Ductless Mini Split Replacement
Mini splits last about 12–20 years. If your system is noisy, inefficient, or needs constant repairs, we can help you upgrade to a newer, quieter, more efficient model. With a mini split replacement, you can enjoy better comfort, zoned temperature control, and lower energy bills.
Furnaces
A furnace is one of the most common heating systems in Blue Ash. It heats air through a heat exchanger and circulates it through your ductwork to keep your home warm and cozy fast. Hill-Air offers complete furnace services, from installation and maintenance to emergency repairs, so you stay safe and comfortable through Ohio’s long winters.
Furnace Installation
If you’re building or upgrading your home’s heating, we’ll help you choose between gas or electric and explain AFUE (Annual Fuel Utilization Efficiency) ratings. A 95% AFUE furnace turns 95% of its fuel into heat, making it both efficient and cost-effective. We size and install your furnace to match your home’s needs and layout.
Furnace Maintenance
It’s best to have your furnace serviced every fall before the cold sets in. We clean burners, inspect the heat exchanger, check gas lines or wiring, and replace filters. Routine maintenance helps avoid costly breakdowns and keeps your home comfortable all season. Our maintenance plan includes fall tune-ups, priority repairs, and savings on service.
Furnace Repair
If your furnace in Blue Ash is blowing cold air, cycling too often, or making strange noises, it’s time to have it checked. Common issues include dirty sensors, worn ignitors, or failing components like the blower motor or heat exchanger. We’ll inspect the system, find the cause, and make the repair quickly so your home stays warm and safe.
Furnace Replacement
Most furnaces last 15 to 20 years. If yours is aging, noisy, or constantly needing service, a replacement might be the smarter choice. We’ll guide you through system sizing, AFUE options, and fuel types to install a furnace that keeps your home comfortable and energy-efficient.
Heat Pumps
We highly recommend heat pumps in Blue Ash because they provide all-electric heating and cooling year-round. In summer, they remove heat from your home; in winter, they bring it in. They’re efficient, quiet, and work especially well in Ohio’s climate. Hill-Air offers full-service heat pump installation, repair, and maintenance so you can enjoy reliable comfort every season.
Heat Pump Installation
Whether you’re going all-electric or building new, we’ll help you select the right heat pump based on SEER2 (for cooling) and HSPF2 (Heating Seasonal Performance Factor). We offer cold-climate and dual-fuel models for extra warmth on frigid days. Our licensed team will install your system for long-term performance and energy savings.
Heat Pump Maintenance
Since heat pumps handle both heating and cooling, they need service twice a year—spring and fall. We clean coils, check refrigerant, inspect reversing valves, and test the system in both modes. Join our maintenance plan for seasonal checkups that help your system last longer and work better.
Heat Pump Repair
If your heat pump is running non-stop, stuck in one mode, or icing over, the problem could be a faulty sensor, defrost board, or reversing valve. We’ll track down the issue and get your system working again.
Heat Pump Replacement
Most heat pumps last about 10–15 years. If yours isn’t heating or cooling like it used to, or if repairs are adding up, we can help you upgrade to a new system with strong SEER and HSPF ratings. A new heat pump means fewer issues, lower bills, and better year-round comfort.
House Too Humid? Allergies Acting Up? Our Indoor Air Quality Services in Blue Ash, OH, Can Help
Clean, healthy air should be something you can count on at home, but between seasonal humidity, dry winter heat, dust, and gas appliances, your indoor air quality can quickly become a problem. In Blue Ash, where weather shifts bring muggy summers and dry, cold winters, your home’s air needs to adjust with the seasons.
We offer professional indoor air quality services for homes across Blue Ash. From filtration to moisture control, we install and repair systems that make your air cleaner, more balanced, and easier to breathe, no matter the time of year.
Air Purifier Installation and Repair
If you’re constantly dusting or dealing with allergies and odors, a whole-home air purifier can help. These systems remove airborne particles before they move through your HVAC system, improving air quality in every room. We install air purifiers directly into your existing system and also provide fast, reliable repairs if your unit isn’t working like it should.
Carbon Monoxide Detector Installation
Gas appliances, fireplaces, and furnaces all come with a risk of carbon monoxide leaks. It’s odorless and invisible—but extremely dangerous. We install carbon monoxide detectors in key locations and test each one for accuracy, giving you reliable early warning if a leak ever occurs.
Dehumidifier Installation and Repair
Summers in Blue Ash can be humid, and that moisture often creeps indoors. Signs like musty smells, sticky air, or even mold suggest your home needs better humidity control. We install quiet, whole-home dehumidifiers that pull excess moisture from the air. If your system isn’t keeping up, we’ll repair or recalibrate it to restore a drier, more comfortable environment.
Humidifier Installation and Repair
In winter, your indoor air can get so dry that it causes dry skin, static shocks, and even damage to wood floors and furniture. A whole-house humidifier adds just the right amount of moisture back into the air. We install these systems to work seamlessly with your furnace, and we repair existing units that aren’t holding proper humidity levels.
Media Air Cleaner Installation and Repair
Media air cleaners go beyond standard HVAC filters, capturing smaller particles like smoke, pet dander, and pollen. If you or a family member suffers from allergies, this upgrade can make a noticeable difference. We install high-efficiency media cleaners, provide replacement filters, and offer repair services to restore airflow and filter performance.
Thermostat Installation and Repair
An outdated or faulty thermostat makes it harder to maintain comfort or save energy. We install modern thermostats, including programmable and smart models, that give you precise control over your indoor environment. And if your current thermostat is acting up, we’ll fix wiring issues, recalibrate sensors, or replace the unit altogether.
UV Air Cleaner Installation and Repair
Looking to reduce airborne germs, mold spores, or bacteria? UV air cleaners use ultraviolet light to disinfect the air as it passes through your HVAC system. We install UV systems for whole-home coverage and repair any issues with bulbs, ballasts, or wiring to keep your protection in place.
UV Light Installation and Repair
UV lights target the dark, damp areas inside your HVAC system—like around coils or air handlers—where mold and bacteria love to grow. Installing a UV light helps keep your system cleaner and your air healthier. If your existing UV light stops working, we’ll replace the bulb and make sure everything is operating as it should.
